Abstract

It was shown that refluxing of europium(III) acetate hydrate with trifluoroacetic acid in a dioxane–acetonitrile mixture gives the polymer {[Eu(μ-OOCCF₃)₃(OH₂)₂]}_n (I) containing dioxane solvate molecules. The reaction of I with [phen(µ-OOC^tBu)₂(OOC^tBu)₂] (II) (phen = 1,10-phenanthroline) in CH₂Cl₂ at room temperature gives a precipitate, the recrystallization of which from acetonitrile affords an unusual trinuclear heterometallic heteroanionic phen₂Zn₂Eu(µ³-OH)(OOC^tBu)₄(OOCCF₃)₂ complex (III). The structure of the products was established from X-ray diffraction data (CCDC no. 2235937–2235939). The optical properties of complex III were studied.

具有 Zn2Eu 金属核的异羧酸盐配合物的合成与光学特性

摘要研究表明，乙酸铕（III）水合物与三氟乙酸在二噁烷-乙腈混合物中回流，可得到含有二噁烷溶胶分子的聚合物{[Eu(μ-OOCCF3)3(OH2)2]}n (I)。I 与[phen(μ-OOCtBu)2(OOCtBu)2](II)（phen = 1,10-菲罗啉）在室温下于 CH2Cl2 中反应生成沉淀，从乙腈中重结晶后得到不寻常的三核杂质金属杂阴离子 phen2Zn2Eu(μ3-OH)(OOCtBu)4(OOCCF3)2络合物(III)。根据 X 射线衍射数据（CCDC 编号：2235937-2235939）确定了产物的结构。研究了络合物 III 的光学性质。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
